Write the expression that means subtract 14 from ๐‘Œ.

Almost immediately, you recognize that weโ€™re doing subtraction, because we have the word subtract.

Now we need to figure out the order that the 14 and the ๐‘Œ go in. The key here is the word from.

โ€œFromโ€ tells us what we are starting with. So if weโ€™re going to subtract 14 from ๐‘Œ, we have to start with ๐‘Œ.

The 14 comes from the ๐‘Œ, which means we start with ๐‘Œ and then we take away 14. We write the expression that means subtract 14 from ๐‘Œ by writing ๐‘Œ minus 14.
